The data on binding energies can be found in the file bedata.dat at the github address of the course

• Write a small program which reads in the proton and neutron numbers and the binding energies

and make a plot of all neutron separation energies for the chain of oxygen (O), calcium (Ca), nickel (Ni), tin (Sn) and lead (Pb) isotopes, that is you need to plot $$ S_n= BE(N,Z)-BE(N-1,Z). $$ Comment your results.
